Abstract
Abstract This invention is in the general field of surgical instruments and relates specifically to an inflatable prosthetic device suitable for use in cardiovascular or endovascular procedures, such as angioplasty, to restore normal blood flow through the vessel. The device is generally a helically wound balloon having a false lumen through its center which is inflatable through its integral inflation lumen.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
116 words
An inflatable vascular prosthesis comprising: an elongate tube having a proximal and a distal end, an outer diameter, a lumen extending from the proximal end to the distal end, said lumen closing at said distal end, wherein at least a part of said elongate tube adjacent the distal end is wound into a helix to form an inflatable tip having a secondary lumen within the helix, where the helix is maintained in a helically wound configuration with polymeric tie strips helically wound about the inflatable tip and which adhere to the helix and where said helix has a deflated outside diameter and a larger inflated outside diameter and where the helix is both inflatable and deflatable.
Claim 2
Dependent Claim
116 words
An inflatable vascular prosthesis comprising: an elongate tube having a proximal and a distal end, an outer diameter, a lumen extending from the proximal end to the distal end, said lumen closing at said distal end, wherein at least a part of said elongate tube adjacent the distal end is wound into a helix to form an inflatable tip having a secondary lumen within the helix, where the helix is maintained in a helically wound configuration with polymeric tie strips helically wound about the inflatable tip and which adhere to the helix and where said helix has a deflated outside diameter and a larger inflated outside diameter and where the helix is both inflatable and deflatable.
Claim 3
Dependent Claim
33 words
The prosthesis of claim 1 wherein the inflatable tip is compressed to form a compressed inflatable tip having an outside diameter no greater than about twice the outer diameter of the elongate tube.
Claim 4
Dependent Claim
26 words
The prosthesis of claim 1 where the helix has a proximal and a distal end and has a radiopaque marker at least at the distal end.
Claim 5
Dependent Claim
19 words
The prosthesis of claim 1 where the helix has a radiopaque marker at both the proximal and distal ends.
Claim 6
Dependent Claim
27 words
The prosthesis of claim 1 where the tubing is wound in adjacent turns making up the helix and the adjacent turns are fused to form the helix.
Claim 7
Dependent Claim
28 words
The prosthesis of claim 1 where the tubing is wound in adjacent turns making up the helix and the adjacent turns are partially fused to form the helix.
